Mark was very informative on his product and comparative to other products pointing out good and bad of each, no high pressure sales tactics, just good old fashioned facts. He was very communicative with the status of the order and installation. His installation crew was outstanding, very maticulous with details of removing the old windows taking care not to do and damage & very detailed in the install. Like one of the guys said, better to take your time and do it right. Left me with some touch up product just Incase it was needed later & I respect that, that was a nice touch. Highly recommended Alamo Exteriors for your replacement window needs, very reasonably priced for aluminum replacement windows, very good quality product, I immediately felt a different during the recent bitter cold we got this January. Thanks Mark

I highly recommend Alamo Exteriors! We are very pleased for several reasons: with their (Mark)'s advise which windows (within our budget) we should install in our home , with how neatly the work crew performed their work, and last but not least, how the windows changed the appearance of our 30 year old house!
